" Ualifornia, have invented certain new and useful improvements inWashing Machines, of which the following is a specification.

My invention relatesto washing machines of the type adapted for use inthe ordinary household wash-tubs. y

'lhe object of my invention is to provide and edective machine capableof ready attachment to, and detachment from the ordinary wash-tub. Afurther object of invention is to, provide for the balancing of themachine in such a manner that its connection with the wash-tub may be ofa simple and easily operated form. fl. still further object is toprovide simple means, without unnecessary exposed moving parts, forproducing the most edective motion of the dasheru @ther objects willbecome apparent from the following specification.

Illt is to be understood, however, that the form and construction of themachine herein illustrated and described may be varied, within thelimits of the claims hereto appended, without departing from the spiritof the invention as expressed in said claims. W' ith this in view myinvention will now be fully described with reference to the aocompanying drawings, wherein Fig. l is a partly broken verticalsectionshowing my machine attached to a wash-tub.

Fig. is a part sectional plan view of the same.

Fig. 3 is a vertical sectional detail, enlarged, of the dasheroscillating mechanism.

lin the drawings, the reference numeral 1 designates a wash-tub of theordinary household type. A frame or bracket 2 is provided with a simpleclamping member, shown in Fig. 1 as a clamping screw 3, adapted tosecure said bracket or frame 2 to the upper edge of one ofthe walls ofthe tub 1. EX- tending from one side of the bracket 2 is a base 4: uponwhich is mounted amotor- 5. The shaft 6 of said motor extends forwardlytherefrom and carries a worm 7 which` drives a worm wheel 8 upon a shaft9, Fig. 2, journalled in the bracket 2.

The worin wheel 8 is provided with a crank pin 10 whichcarries atrunnion block 1l slidable in a bifurcated arm 12, Figs. 1 'and 2, saidarm being secured upon an oscillatory shaft 13. Said shaft has secured.to its opposite end a collar 14, Figs. 2 and 5. A forwardly extendingcurved lever or arm 15 is removably secured to said collar 1d by meansof a set screw 16. rlfhe outer or forwardend of said arm 15 thus has anup and down arcuate reciprocating motion. The worm gearing and thebifurcated arm 12 are enclosed in a housing 17, Figs. 1 and EZ,preferably formed as apart of the bracket 2.

'fl fixed arm or bracket 18 entends forwardly from the housing 17 andcarries atv its outer end a guide member 19, said guide member beingmounted in said fixed arm 18 for oscillation in a vertical plane bymeans of a pin and socket connectionv indicated at 2O in Fig. 2. rllhemember 19 provides a d@ guide for a vertically slidable spindle 21, Fig.1, which carries at its lower end a dasher 22 of any suitable form. 'lhespindle 21 is connected with the reciprocating arm 15 by mechanism whichimparts both up and down movement and horizontal oscilla tion to thedasher 22.

rlhis mechanism comprises a collar 23, Figs. 1, 3, d and ti, mounted forhorizonal oscillation in a trunnion block 2t and secured W to thespindle 21 by means of a set screw 25, Figs. 1 and 6. 'llhe trunnionblock QA: is mounted for vertical oscillation by means of journal pins26 in the forked or hollow end 15 of the arm 15. Said trunnion blockv 95,24 is provided with upwardly and rearwardly projecting lugs 27, whichcarry a pawl 28, Figs. 3 and d. Said pawl is adapted to engage a ratchetwheel 29 carried by a grooved cam 30, Fig. 6, said cam being rotatably10 mounted in the forked end 15 of the arm 15. The collar 23 securedupon the spindle 2l carries a cam roller 31 adapted to ride in thegroove of said cam 30. rll`hus as the arm 15 moves up and down in anarcuate N path, and as the spindle 21, which also moves up and down withsaid arm, is guided by the member 19 at a point below the connectionbetween said. arm and said spindle, there is set up a relativeoscillation or angular movement between said arm and said spindle, andthis relative angular movement causes the nervi a step by step motion.cam produces a bo sontal c" spindle 2l dasher 2:2 carri reby, s only tereciprocate veiticall oscillate horizontally, and o tion is producedentir ly by tical reciprocation ci me l5. the mechanism above describedclosed, as shown, by the fori; 15 of the ln order to fi a Wringer et the"usual weil in A clutch mechanism, indicated in Fig. 2, and illustratedin detail in 'T f upon the ena' of e. contini shaft 9. Said clutchinecbnani.v jaw member 32 secured upc Le end of the shaft 9, and acompleinen?UL y jaw member 33 secured., as by a set screw.7 upon theWring'er sl t upon which is carried one of the usan.. `llvringer rollsThe Wringer shaft 35 is axially movable and is carried by a. sleevesurrounding the clutch members' 32 and slidable upon. the journal sleeve38 et the 9. A latch is provided for retaining said sleeve in itsinnermost position, as shown by dotted lines in Fig. in which positionthe clutch members 32 and are mutually engaged. lt is understood thatthe Wringer may be secured to the 'Wash-tub 'i in the usual manner, andas the details of said Wringer do not enter into the present invention,has been omitted from the drawings, thc roll 36 being sufficient toillustrate the connection established by the clutch mechanism abovedescribed between, the shaft 9 and the Wringer.

lt is to be observed that the Weight of the machine is approximatelysymmetrical on both sides of the su porting bracket 2 thereof, the motor5 serving to counterbalance the Weight of the dasber Q2 and itssupporting and operating arms. @n account of this balancing of theWeight, the bracket 2 can be easily secured to the Wall ot the tub l bythe simple clamp shown, thus rendering the zittachment and detachment ofthe machine to and from the tub relatively easy.

For the purpose of heating the Water in the tub l, or for maintaining,rsaid Water at the desired `Itemperature durinfr .the operation of themachine, l may employ an electric immersion heater, of any suitable andWell known form, as indicated at e() in Fig. l of the drawings.

Having thus described my invention, what I claim' and desire to protectby Letters Patent of the United States is i not but also to doublemorotating i comprises Washing' .machi:.. membei'i; a sutrpendnlousycari: t l movable there` posed parallel with t guide'tor the e ed by therelative a.. between said ancA s parting horizontal anguw tion to saiddash 2. la Washing machine porting member; subs.. ne.' -rticallj/reciprocating arm extending Afrom; dasher pendulously carri by said ermand vertically movable therevi'h: and a paul and ratchet cani mechanismactuated the relative svinging mover f betivcez" said arm and said das`mentally oscillating said flasher.
